What exactly is Aerosol hearth extinguishing
What on earth is aerosol hearth extinguisher? Aerosol fireplace extinguishing engineering is a brand new form of hearth extinguishing technologies formulated on the basis of armed service pyrotechnics.
The very first era of aerosol fireplace extinguishing technologies was born within our state, often known as smoke fireplace extinguishing technologies, which started from the early 1960s. It was accomplished by scientific scientists from the Tianjin Fire Investigate Institute of Public Safety, who independently formulated an computerized smoke fire extinguishing method, which is principally accustomed to extinguish fires at school A, B, and C liquid storage tanks.
During the early nineteen eighties, Using the emergence of environmental safety troubles of “halon fireplace extinguishing agent”, discovering alternate options to halon turned an essential investigation matter.
At the end of the eighties, Russian experts to start with succeeded in looking into aerosol fireplace extinguishing technology that may extinguish fires inside a submerged manner, which opened up a brand new way for halon substitution study. Subsequently, aerosol fire extinguishing technology has captivated the eye on the Global Neighborhood, and nations such as China, the United States, Australia, Malaysia and other nations around the world have also started investigate on new aerosol fireplace extinguishing technologies.
Generally speaking, aerosol is usually a secure condition system fashioned with the dispersion of fantastic strong or liquid particles in a fuel. Skillfully, it refers into a colloidal program that utilizes gas (ordinarily air) as being the dispersion medium and reliable or liquid particles because the dispersant.Common aerosols in mother nature—clouds, smoke, fog, and so forth.The size of your particles in aerosols is usually inside the order of ten-5 to ten-1μm, which has gasoline fluidity and will diffuse all around obstructions.
The medicament within the aerosol fireplace suppression program gadget is strong, as well as element emitted from the medicament in the oxidation-reduction reaction is aerosol. The first era of aerosol fire extinguishing know-how-smoke fire extinguishing technological innovation.
K-type aerosol fire extinguisher, also referred to as potassium salt fireplace extinguishing technologies, is the next phase of the development of aerosol fire extinguishing know-how, which began in the former Soviet Union while in the mid-1960s. Our region begun late On this regard, setting up within the early nineties.
In such a aerosol producing agent, potassium nitrate is principally made use of as the primary oxidant. Its sprays have substantial fire extinguishing effectiveness, but because they consist of a great deal of potassium ions, Quick to soak up humidity, forming a yellow and sticky powerful alkaline conductive liquid film, this substance may be very harming to electronic devices, so K-form aerosol computerized fire extinguishing device can't be Utilized in Digital products, precision devices and cultural relics Archive area. At the moment, the use available in the market is little by little reducing.
The third-generation aerosol (S kind) is mainly made from strontium salt as the primary oxidant. In contrast to the second-technology potassium salt (K-variety) aerosol, strontium ions will not take in dampness, tend not to kind a conductive Resolution, and will never lead to damage to electrical tools. In 2001, China Cellular Communications Corporation selected the strontium salt aerosol (S-style aerosol computerized fireplace extinguishing product) produced by the organization right after rigorous inspection and verification to safeguard its communication foundation stations and also other locations Geared up with subtle Digital tools.
At present, strontium salt aerosol products are actually utilized in A huge number of engineering projects, as well as 3rd-era aerosol has become more and more recognized by consumers
Aerosol fire extinguisher software variety
a. Electrical fireplace
Communication home, conversation foundation station, electronic Laptop or computer area, etc.;
Electrical fires in locations made up of precision instruments and products, like electric power distribution rooms, generator rooms, cable interlayers, cable wells, cable trenches, and so on.
b. Good surface area fireplace
Surface hearth of combustible good resources in places the place combustible solid elements are utilized or stored.
c. Liquid fireplace
Liquid fires in locations where by diesel oil is created, applied or saved (except -35 diesel), weighty oil, transformer oil, animal and vegetable oil and other flammable liquids of Class C; In advance of extinguishing a fuel fire, the gas supply may be Minimize off.
Aerosol hearth suppression method application .
d. The S-form aerosol fireplace extinguishing device can not be accustomed to place out the subsequent fires
1. Substances which might be oxidized with out air, including nitrocellulose, gunpowder, and many others.; Lively metals, which include potassium, sodium, magnesium, titanium, etc.; compounds that may decompose by on their own, including specific peroxides, hydrazine, and so on. Metal hydrides, like potassium fluoride, sodium hydride, and so on. Organic substances, including phosphorus. Powerful oxidants, including nitrogen oxide, fluorine, and so on.
2. Deep fire of combustible solid materials.
3. Fireplace in crowded destinations, for example theaters, auditoriums, and so forth.
4. Fire in places with explosion hazard, such as workshops with explosive dust.
5. Ultra-clean atmosphere, like pharmaceutical workshops, chip processing places, medical rooms, etcetera.
Aerosol fireplace extinguishing Doing work principle
The 4 things of combustion: combustibles, oxidizer, temperature and uninhibited chain reaction. The fire extinguishing system of fire extinguishing fuel will be to remove a single or a number of of the 4 factors of combustion.
The solid hearth extinguishing agent inside the S-type aerosol hearth extinguishing unit is started by electric power, and it undergoes redox reaction to variety a lot of agglomerated fireplace extinguishing aerosols, and its composition is principally N2, a little volume of CO2, and metal salt reliable particles.
Aerosol fire extinguishing system is as follows
System of endothermic cooling and hearth extinguishing
Metallic salt particles absorb a large amount of warmth at high temperatures, and undertake Bodily endothermic procedures for instance thermal melting and gasification. The flame temperature is lowered and afterwards radiated towards the combustible combustion area for gasification of combustible molecules and vaporized combustible molecules. The heat of pyrolysis of combustion molecules into no cost radicals will lower, as well as combustion reaction pace are going to be suppressed to a certain extent.
